Father Lambert (Wyrley Birch), a priest, is shot dead on a Bridgeport, Connecticut street at night. The police, led by Chief Robinson (Lee J. Cobb), fail to immediately find the murderer. It soon becomes a political hot potato, with the police accused of incompetence, and the city's reform-minded administration comes under attack. Robinson and the prosecutor Henry Harvey (Dana Andrews) come under severe pressure by political leaders to find the killer or bring in outside help.
